ADC574 Burr-Brown Corporation, ADC574 Datasheet - Page 3

• Manufacturer Part Number: ADC574
• Description: Microprocessor-compatible Analog-to-digital Converter
• Manufacturer: Burr-Brown Corporation

SPECIFICATIONS
ELECTRICAL
At T
* Same specifications as ADC574AJP, AJH, ASH.
NOTES: (1) With fixed 50
Adjustments section). (2) FS in this specification table means Full Scale Range. That is, for a 10V input range, FS means 20V; for a 0 to +10V range, FS means
10V. The term Full Scale for these specifications instead of Full-Scale Range is used to be consistent with other vendors' 574 and 574A type specifications tables.
(3) Using internal reference. (4) See Controlling the ADC574A section for detailed information concerning digital timing. (5) External loading must be constant during
conversion. The reference output requires no buffer amplifier with either 12V or 15V power supplies.
